BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be specifically described with reference to the drawings showing the embodiments.
(First Embodiment)
FIG. 1 shows a configuration example of the in-vehicle communication system according to the present invention. In the example shown in FIG. 1, a low-speed LAN (first network) L1 and a high-speed LAN (second network) L2 are connected to a gateway (communication connection device, conversion value determiner) 10. In this description, the high-speed LAN (L2) has an HM (Human Machine Interface) unit 30, and the low-speed LAN (L1) has a body ECU (Electronic Control Unit) 34.
[0022]
The gateway 10 is connected to a low-speed bus and controls communication with a device connected to the low-speed bus. The gateway 10 is connected to a high-speed bus and controls high-speed communication to control communication with a device connected to the high-speed bus. A control unit 12 connected to the low-speed communication unit 16 and the high-speed communication unit 18 for controlling communication between the low-speed communication unit 16 and the high-speed communication unit 18; and a storage unit connected to the control unit 12 and storing information. 14 is provided. The storage unit 14 includes a nonvolatile memory such as a flash memory.
[0023]
The HM unit 30 includes a display unit (output unit) 30a such as a liquid crystal display panel, an input unit 30b such as a plurality of button switches, and a communication unit (not shown) to which a high-speed bus is connected. The input information input to the gateway 30b can be transmitted to the gateway 10, and the display information received from the gateway 10 can be displayed on the display unit 30a. In this description, when a display request for a weight point, which will be described later, is received by the input unit 30b, the received display request is transmitted to the gateway 10. When a weight point is received from the gateway 10, the weight point is displayed on the display unit 30a.
[0024]
The body ECU 34 includes a communication unit (vehicle weight transmitter) 34a to which a low-speed bus is connected, and mainly controls various devices related to the body (vehicle). A suspension control unit 36 is connected to the body ECU 34. The suspension control unit 36 operates as a body weight detector that outputs a detection value corresponding to the body weight applied to the suspension to the body ECU 34. The body ECU 34 can transmit a vehicle weight based on the detected value in response to a request received from the gateway 10.
[0025]
The storage unit 14 of the gateway 10 stores in advance a reference weight (conversion information) serving as a reference for the vehicle body weight. The reference weight is the weight of the vehicle body, and is stored in the storage unit 14 in advance at the time of manufacture, for example. In this description, since the weight of the vehicle body is detected at the suspension portion, the weight of the vehicle body and the reference weight do not include the weight of a tire or the like. Further, the storage unit 14 stores a correspondence relationship (hereinafter, referred to as a point table) between an increment of the vehicle body weight with respect to the reference weight (hereinafter, referred to as a weight increment) and a weight point. FIG. 2A shows an example of the point table (conversion information). In the example of FIG. 2A, weight increments are classified and weight points are set for each rank. The larger the weight increment, the higher the weight point is set.
[0026]
The control unit 12 of the gateway 10 operates as means for requesting and acquiring the body weight from the low-speed communication unit 16 to the body ECU 34 when the high-speed communication unit 18 receives the display request of the weight point from the HM unit 30. Further, the control unit 12 operates as a unit that determines a weight point (converted value) according to the vehicle body weight received by the low-speed communication unit 16. In the present description, the control unit 12 calculates the difference (weight increment) between the received vehicle weight and the reference weight, and extracts a weight point corresponding to the calculated weight increment from the point table. The control unit 12 transmits the determined weight points from the high-speed communication unit 18 to the HM unit 30.
[0027]
Further, the storage unit 14 stores a cumulative value of weight points (hereinafter, referred to as a cumulative point). The control unit 12 adds the determined weight points to the accumulated points stored in the storage unit 14.
[0028]
Next, display of weight points using the in-vehicle communication system according to the present invention will be described.
FIG. 3 shows an example of a procedure for displaying weight points. When the input unit 30b of the HM unit 30 receives the display operation of the weight point, the HM unit 30 requests the gateway 10 to display the weight point (S10). When the high-speed communication unit 18 receives the display request from the HM unit 30, the control unit 12 of the gateway 10 requests the body ECU 34 from the low-speed communication unit 16 for the body weight (S12). The body ECU 34 transmits the vehicle body weight to the gateway 10 in response to a request from the gateway 10 (S14).
[0029]
The control unit 12 of the gateway 10 calculates the difference (weight increment) between the vehicle weight received by the low-speed communication unit 16 and the reference weight stored in the storage unit 14 (S16), and according to the calculated weight increment. The weight points are determined based on the point table stored in the storage unit 14 (S18). In addition, the control unit 12 adds the determined weight points to the cumulative points stored in the storage unit 14 to update the cumulative points (S20). The control unit 12 transmits the determined weight points and the updated cumulative points to the HM unit 30 from the high-speed communication unit 18 (S22).
[0030]
The HM unit 30 that has received the weight points and the accumulated points from the gateway 10 displays the received weight points and the accumulated points on the display unit 30a (S24). For example, when the weight point is “5” or “7”, a warning message can be displayed.
[0031]
In the above-described embodiment, the weight points are displayed. However, for example, as shown in FIG. 4, the weight increment can be displayed as it is. In the example of FIG. 4, the weight increment is calculated in the same manner as in the above-described embodiment (S10 to S16), and the calculated weight increment is transmitted to the HM unit 30 (S30) and displayed (S32).
[0032]
Instead of using the point table, for example, every time the weight is increased by 100 kg from the reference weight, the weight point can be increased by one. For example, when the weight increment is 658 kg, the control unit 12 can determine the weight point to be “6”. In this case, the storage unit 14 stores conversion information such as “100 kg = 1 point” instead of the point table.
[0033]
(Second embodiment)
The weight point can be increased according to the traveling amount. FIG. 5 shows a configuration example of the in-vehicle communication system according to the present invention. The in-vehicle communication system shown in FIG. 5 has a configuration similar to that of the first embodiment (FIG. 1). However, a body weight detector 37 that outputs a detection signal according to the body weight is connected to the body ECU 34. The detection of the vehicle body weight can be performed by an arbitrary method. For example, a vehicle body weight detector 37 can be provided at a damper portion of the suspension. The body ECU 34 transmits a vehicle weight based on a detection signal output from the vehicle weight detector 37 in response to a request received from the gateway 10.
[0034]
The body ECU 34 is connected to, for example, a traveling distance measuring device 38 that measures the number of rotations of the wheels, and outputs a measurement signal of the number of rotations of the wheels to the body ECU 34 from the traveling distance measuring device 38. The communication unit (travel distance transmitter) 34a of the body ECU 34 transmits the travel distance based on the measurement signal in response to a request received from the gateway 10. Here, the traveling distance is a distance accumulated based on, for example, purchase of a vehicle.
[0035]
The low-speed LAN (L1) has an engine ECU 32. Although not shown, the engine ECU 32 includes a communication unit to which a low-speed bus is connected, and mainly controls various engine-related devices. The engine ECU 32 transmits a change notification of ignition on / off (engine operation / stop) to the gateway 10.
[0036]
The storage unit 14 of the gateway 10 stores the correspondence (point table) between the weight increment and the travel distance and the weight points. Here, the traveling amount is a traveling distance from when the ignition is turned on to when the ignition is turned off. FIG. 6 shows an example of the point table. In the example of FIG. 6, the weight increment and the traveling amount are classified into ranks, and weight points are set for each rank. The weight point is set to a higher value as the weight increment increases, and the weight point is set to a higher value as the travel distance increases for the same weight increment.
[0037]
The control unit 12 of the gateway 10 requests the mileage from the low-speed communication unit 16 to the body ECU 34 when the low-speed communication unit 16 receives the change notification to the ignition on or the change notification to the ignition off from the engine ECU 32. Works as The control unit 12 stores the traveling distance received by the low-speed communication unit 16 in the storage unit 14. Hereinafter, the travel distance requested and accepted when the ignition is turned on is referred to as a starting travel distance, and the travel distance requested and received when the ignition is turned off is referred to as an end travel distance.
[0038]
The control unit 12 calculates a difference (travel distance) between the start travel distance and the end travel distance received by the low-speed communication unit 16, and calculates a weight point corresponding to the calculated travel distance and the vehicle weight received by the low-speed communication unit 16. Acts as a means of determining. The control unit 12 calculates a difference (weight increment) between the received vehicle weight and the reference weight, and extracts a weight point corresponding to the calculated weight increment and travel distance from the point table.
[0039]
7 and 8 show examples of the procedure for displaying the weight points. When the low-speed communication unit 16 of the gateway 10 receives a notification that the ignition has been turned on from the engine ECU 32 (S2), the control unit 12 requests the traveling distance from the low-speed communication unit 16 to the body ECU 34 (S4). The traveling distance (starting point traveling distance) transmitted from the ECU 34 (S6) is received (S8) and stored in the storage unit 14.
[0040]
When the input unit 30b of the HM unit 30 receives the display operation of the weight point, the HM unit 30 requests the gateway 10 to display the weight point (S10). When the high-speed communication unit 18 receives the display request from the HM unit 30, the control unit 12 of the gateway 10 requests the body ECU 34 from the low-speed communication unit 16 for the body weight (S12). The body ECU 34 transmits the vehicle body weight to the gateway 10 in response to a request from the gateway 10 (S14).
[0041]
The control unit 12 of the gateway 10 calculates the difference (weight increment) between the vehicle weight received by the low-speed communication unit 16 and the reference weight stored in the storage unit 14 (S16), and according to the calculated weight increment. The weight points are determined based on the point table stored in the storage unit 14, and the determined weight points are transmitted from the high-speed communication unit 18 to the HM unit 30 (S40). The HM unit 30 that has received the weight points from the gateway 10 displays the received weight points on the display unit 30a (S42).
[0042]
When the low-speed communication unit 16 of the gateway 10 receives a notification that the ignition has been turned off from the engine ECU 32 (S44: YES in FIG. 8), the control unit 12 of the gateway 10 transmits the travel distance from the low-speed communication unit 16 to the body ECU 34. (S46), and receives the travel distance (end travel distance) transmitted from the body ECU 34 (S47). The control unit 12 calculates the travel distance from the start travel distance and the end travel distance (S48), and stores the calculated travel distance and the weight points according to the calculated weight increment in the point table stored in the storage unit 14. It is determined again on the basis of (S50). Further, the control unit 12 updates the cumulative points by adding the re-determined weight points to the cumulative points stored in the storage unit 14 (S52). The control unit 12 transmits the re-determined weight points and the updated accumulated points from the high-speed communication unit 18 to the HM unit 30 (S54).
[0043]
The HM unit 30 that has received the weight points and the accumulated points from the gateway 10 displays the received weight points and the accumulated points on the display unit 30a (S56).
[0044]
In the example shown in FIGS. 7 and 8, the weight point in which the travel distance is not considered is displayed (S42) in response to the display request (S10), but the ignition is turned off regardless of the display request. In this case (S44: YES), it is also possible to automatically display the weight points and the total points in consideration of the traveling amount (S56).
[0045]
In each embodiment described above, the accumulated points stored in the storage unit 14 can be displayed on the HM unit 30, for example. For example, when the high-speed communication unit 18 receives the browsing request signal transmitted from the input unit 30b, the control unit 12 reads the requested cumulative points from the storage unit 14 and transmits the accumulated points to the HM unit 30 from the high-speed communication unit 18. It is possible to do. For example, it is possible to increase or decrease the insurance premium of car insurance or increase or decrease the rental car fee based on the size of the accumulated points.
[0046]
In the above-described embodiment, the difference (weight increment) between the vehicle weight and the reference weight is determined. For example, the correspondence between the vehicle weight and the weight points is stored in a point table, and the control unit 12 A weight point corresponding to the vehicle body weight received from the body ECU 34 can be extracted from the point table.
[0047]
Further, in the above-described embodiment, the body weight and the traveling distance are transmitted from the body ECU 34, but the transmission of the body weight and the traveling distance can be transmitted from any vehicle-mounted device. Further, in the above-described embodiment, the gateway 10 determines the conversion value according to the vehicle body weight, or the vehicle weight and the traveling amount, but it is also possible to determine the conversion value using any vehicle-mounted device.
